On all the large wooded rivers and streams. 

 *981. Lartis ridibtotdtts, Lin. 



This bird, which Mr. Howard Sanders has kindly identified, was shot 

 near the junction of the Dunsiri and Brahmaputra in December. From 

 the colour of its bill and legs it rather puzzled me, for I was well acquainted 

 with brunneicepliala, which is a common gull on the above river. It is 

 interesting finding the laughing-gull so far up the Brahmaputra, at this 

 point some 500 miles from the sea. Jerdon mentions its being abundant 

 at the mouths of the Hanges. 



*987. Sterna melanogastra, Temminck. 



A very common tern on the Brahmaputra and its larger tributaries, 

 such as the Dikrang, as far up as sand-banks occur.
